"Three streaks of falls"

The image appears to move.

"Metalic time tunnels"

The left image appears to rotate counterclockwise while the right one clockwise. However, the reversal is observed when we watch this image by keeping blinking.

Copyright Akiyoshi .Kitaoka 2006 (February 10)

Warning: Do not keep blinking too frequently. Blink vibrates the retinas in the eye balls, which might possibly cause serious disorders, e.g. retinal detachment or hemorrhage of the fundus for those who have too strong nearsightedness, high blood pressure or diabetes.


"Flickering rotating snakes"

The rings appear to rotate though only two images alternate actually.

The yellow circle appears to expand.

Namahage (see the December corner)


"Rotating snakes: gradation version"

Each ring appears to rotate slowly without effort. In this case, the direction of rotation is constant. When observers keep blinking, each ring appears to rotate quickly. In this case, the direction of rotation is not constant. Attention can change the direction.

Warning: Do not keep blinking too frequently. Blink vibrates the retinas in the eye balls, which might possibly cause serious disorders, e.g. retinal detachment or hemorrhage of the fundus for those who have too strong nearsightedness, high blood pressure or diabetes.

One of my colleagues suggested that the gradient version gives more illusion magnitude than the edge one. Then I have tried to make this work. Do you feel stronger illusion that the original? (I do not...)

This idea has been published in: Journal of Vision Volume 5, Number 11, Article 10, Pages 1055-1069

"Ritsumeikan jitter illusion"

(Ritsumeikan) appears to jitter when the surround flips in contrast. Many observers possibly do not see this illusion.

cf. visual jitter


"Dizziness"

Both rings appear to rotate clockwise. Moreover, the left ring appears to contract while the right one appears to expand.

"Rotating eyes of a dog"

The left ring may appear to rotate clockwise while the right one counterclockwise. However, keeping blinking reverses these directions.

Copyright Akiyoshi .Kitaoka 2005 (November 6)

One of the works that were not adopted for New Year's card designs.

Warning: Do not keep blinking too frequently. Blink vibrates the retinas in the eye balls, which might possibly cause serious disorders, e.g. retinal detachment or hemorrhage of the fundus for those who have too strong nearsightedness, high blood pressure or diabetes.
